The CPU & Microprocessors: Purpose

Which sequence best describes the CPU's core operation cycle?

• Input → Execute → Decode

• Fetch → Decode → Execute

• Decode → Fetch → Output

• Input → Process → Output

In computing, what is a microprocessor?

• A removable storage device

• A type of integrated circuit on a single chip

• A mechanical part that cools the CPU

• A collection of separate circuits on multiple boards

Which example correctly matches the Input-Process-Output model described?

• Input: monitor displays a result; Process: keyboard adds numbers; Output: CPU reads instructions

• Input: user types a number with a keyboard; Process: the ADD instruction adds the input to an existing value; Output: result is shown on the monitor

• Input: CPU fetches and decodes; Process: monitor displays; Output: keyboard sends data

• Input: mouse moves cursor; Process: CPU fetches; Output: printer warms up

Which statement best explains the purpose of the CPU in a computer system?

• To store permanent data and files

• To fetch, decode, and execute instructions, processing data into outputs

• To provide power to input and output devices

• To only manage graphics on mobile devices

Which option correctly represents the typical sequence followed by computer systems as shown in an Input-Process-Output diagram?

• Output → Input → Process

• Input → Output → Process

• Process → Input → Output

• Input → Process → Output

A sensor records temperature data that is then filtered and used to trigger a fan. In terms of the Input-Process-Output model, which part is the 'Process'?

• The sensor capturing temperature

• The filtering and decision logic

• The fan turning on

• The temperature value displayed to the user

In the Von Neumann Architecture diagram, which components directly interact with the processor through buses?

• Main memory and input/output controllers

• Secondary storage and output devices only

• Control unit and arithmetic logic unit only

• Registers and secondary storage only

Which set lists core elements that the Von Neumann architecture consists of?

• Control unit (CU), Arithmetic logic unit (ALU), Registers, Buses

• GPU, Cache, Heat sink, Power supply

• Keyboard, Mouse, Monitor, Printer

• Hypervisor, Virtual machines, Containers, Orchestration

What is the role of the Von Neumann Architecture according to the overview?

• It outlines how computer memory, input/output devices, and the processor work together

• It defines how to design user interfaces for applications

• It specifies rules for internet communication protocols

• It replaces the need for main memory in modern systems

Which component pair forms parts of the CPU within the Von Neumann Architecture?

• Control unit (CU) and arithmetic logic unit (ALU)

• Main memory and secondary storage

• Input devices and output devices

• Buses and registers only
